How do I formulate the on conflict do update-section of this query? When I
try set title=q.title, q is unknown. When I try and change 'title' in the
select-part to something else and try title=ti I get the message that ti
cannot be used in this part of the query.
INSERT INTO wos_2017_1.article (ut,
title,
author_count)WITH p AS (
SELECT
ARRAY [ ARRAY [ 't', 'some_namespace' ] ] AS ns),
q AS (
SELECT
ut,
unnest (xpath ('//t:title[@type= "item"]/text()',
xml,
p.ns))::text title,
unnest (xpath ('//t:summary/t:names/@count',
xml,
p.ns))::TEXT::INTEGER AS author_count
FROM
p,
source.cover_2016)SELECT
ut,
regexp_replace (regexp_replace (regexp_replace (title, '<', '<',
'g'), '&', '&', 'g'), '>', '>', 'g')
title,
author_countFROM
q
ON CONFLICT (ut)
DO UPDATESET
title = title,
author_count = author_count;
